Most babies settle into the conventional
head-down(cephalic) position in the womb by about 32 - 34
weeks. However, some babies remain bottom down inside your
womb. Such babies are called breech babies.

Since a breech baby lies bottom down in the womb, the
legs are delivered first followed by the head. Some
complications may arise when the head is being delivered.
In normal cephalic cases when the baby is delivered head
first, the remaining body just slides out of the womb.
However, in breech babies, the vagina is not stretched
enough with the delivery of the legs, and hence the head,
which is the biggest part of the body to be delivered, may
get stuck during the second stage of labour. Therefore, an
episiotomy may be required before the head is delivered
vaginally. Forceps (or assisted delivery) are commonly
used.

When the baby is in such a position that a vaginal
delivery cannot be attempted, you may be offered a
caesarean.
